The invention discloses an isobaric liquid injection device of an automobile lithium battery liquid injection machine, and belongs to the technical field of lithium battery production equipment. The isobaric liquid injection device comprises a supporting assembly, a liquid injection assembly is arranged on the inner side of the supporting assembly, and the surface of the liquid injection assembly is sleeved with a first linkage assembly. According to the invention, a second hydraulic cylinder is controlled to operate through a designed trigger assembly and the designed liquid injection assembly, in the working process of the second hydraulic cylinder, the output shaft of the second hydraulic cylinder can drive a first insection panel to transversely move, through the linkage effect between the first insection panel and an outer insection surface, a built-in adapter barrel can drive a movable conical barrel to quickly rotate in the fixed circular barrel, electrolyte entering the fixed circular barrel enters along a drainage pipeline on the tangent plane, gas mixed in the electrolyte can be effectively removed under the action of centrifugal force, the defoaming effect can be achieved at the same time, and the efficiency of injecting electrolyte into the battery shell can be improved.
Description
technical field [0001] The invention belongs to the technical field of lithium battery production equipment, in particular to an isobaric liquid injection device for an automobile lithium battery liquid injection machine. Background technique [0002] Subsidies for new energy vehicles will increase the cruising range of vehicles and increase the energy density of battery packs. The lowest gear standard is increased from the original 100km to 150km, and the highest gear is raised from the original 250km to more than 400km. In the production process of automotive lithium batteries, it is necessary to use liquid injection equipment to inject the electrolyte into the battery casing. At present, the existing liquid injection equipment for automotive lithium battery production still has some shortcomings in the process of use. In order to Improving the efficiency of liquid injection is generally achieved by extracting the internal pressure of the battery case. Since the electroly...
